OIL-LUBRICATOR.

Application filed December 31, 1919.

To all whom it may concern Be it known that I, PAUL JACOT, a citizen of the Swiss Republic, residing at Place Neuve, 8a, La Ohaux-de-Fonds, Switzerland, have invented new and useful Improvements in Oil-Lubricators, of which the following is a specification.

The subject or the present invention is an oil lubricator comprising an oil cup provided with a cover having a filling opening. The feature or the lubricator is that the cover is mounted for rotation on the oil cup and connected to the latter in non-detachable fashion, the filling opening being eccentric in relation to the axis of rotation of the cover and ordinarily closed by a movable.

closing pin located within the oil cup and under the action of elastic means tending continuously to maintain the closing pin in engagement with the filling opening of the cover, and tending to hold the cover in fixed position.

One embodiment of the invention is illustrated in the drawing by way of example. Figure 1 is a longitudinal section on the line A-B of Fig. 3, the filling opening of the lubricator being closed. Fig. 2 is a section on the line CD of Fig. 4, the lubricator being shown ready for filling. Figs. 3 and a are plan views respectively of Figs. 1 and 2.

The oil lubricator shown in the drawing comprises a cylindrical oil cup (1 intended to fit with its tubular end a in the journal of the member to be lubricated. Z2 is the outlet opening of the oil cup. The oil cup a is surmounted by a cover 0 formed by a cap fitted in such manner that it can rotate, but cannot be detached. To this end the aim 0 of the cap is arranged to slide freely on a flange (Z on the oil cup. The cover 0 is formed with a circular opening 6 for introduction of the liquid lubricant into the oil cup. This opening is eccentric in relation to the axis of rotation of the cover 0 and is beveled of? on the inner side of the latter.

On the upper edge of the oil cup a is fitted a ring f; the latter is flush with the said edge so that the cover fits perfectly and presents an internal extension provided with a circular opening in which is fixed a socket member g. The internal diameter of the socket member 9 and that of the open- Specification of Letters Patent.

ing 6 are equal; moreover, the axes of the socket member and of the opening are equidistant from the axis of rotation of the cover 0. In the socket g is freely mounted the closing pin 71. having a shoulder 2'. On the lower end of this pin is fitted a coil spring is bearing at one end against the collar z' and at the other against the bottom of the oil cup at. The spring is tends continuously to push the closing pin it up" ward and to maintain the collar 2' pressed against the lower edge of the socket g. The closing pin occupies this position when the opening 6 in the cover coincides therewith. The upper end of the pin which is rounded is then engaged in the opening 0 and proj ects slightly beyond the outer edge as shown in Fig. 1. Two results are thus obtained; first, the pin it insures the tight closure of the opening 6 and in addition it looks the cover 0 in such manner that it cannot be rotated on the oil cup.

To permit filling of the lubricator the closing pin is pushed inwardly by pressing the finger on the end which projects beyond the cover. lVhen the rounded part of the pin reaches the level of the inner edge of the opening 6 the cover 0 is turned through about 180 for example as indicated by the arrow in Fig. 4. The opening 6 then communicates with the interior of the oil cup permitting the filling of the latter while the pin presses against the inner surface of the cover 0 and maintains the spring k compressed as shown in Fig. 2. hen the filling of the lubricator is completed the cover 0 is again turned to bring the opening 6 opposite the closin pin it which reengages it as shown in Fig. 1 under the action of the coil spring is.

Having now particularly described and ascertained the nature of my said invention and in what mannerthe same is to be performed, I declare that what I claim is:

1. An oil cup, comprising a tubular member, a rotatable cover secured thereto and having a filling opening disposed eccentrically with relation to the axis of the cup, and a spring-pressed pin located within the cup in the path of said opening for engagement therewith thereby to lock the cover against rotation.

2. An oil cup, comprising a tubular member, a cover mounted for rotation thereon against rotation, and means for limiting the sliding movement of said pin.

In testimony whereof I have signed my name to this specification.
